Step 2: Preheat oven to 350 degrees. In a pan, melt the butter. Add the flour and mix. Let cook about 3-5 minutes stirring the roux every 30 seconds or so.
Step 3: Add in the chicken broth and mix into the roux. Add in the cream cheese. Allow the cream cheese to melt in. Add in the sour cream and mix. Add in the cumin and green chilis and mix in. Allow the sauce to simmer and thicken for about 5 minutes.
Step 4: Pour about half of the white enchilada sauce into the casserole dish. Roll the chicken and about 1 tablespoon of cheese into each tortilla. Place the enchiladas into the sauce. Pour the rest of the sauce over the enchiladas.
Step 5: Spread the rest of the green chilis on top of the enchilada sauce. Spread the rest of the cheese on top of the entire dish. Bake 25-27 minutes. Serve immediately.
